METHOD OF MANUFACTURING MAGIC CANDLES.

No Drawing.

This invention refers to so-called magiccandlcs, that is to say toy candles which upon burning or by the evolution of smoke produce certain illusional, pyrotechnic or similar effects, colored fireworks'or the like,

and it is an object of my invention to produce a superior article of the kind referred to and to generally improve and perfect the process of manufacture thereof. As heretofore practised the process of manufacture was commonly effected by inserting a plurality, for instance hundred or any other suitable number of properly cut and straightened wires in wooden supporting frames which with the wires secured thereto were then immersed in a liquid combustible compound. After the immersion the frames were removed to drying chambers from which they were again withdrawn aftena few hours, and were then submitted to another immersion, followed by another drying stage of the frames with the wires in the drying chambers. sumed a great amount of time and labor, the second drying stage likewise requiring several hours. With the liquid combustible compound there is the additional inconvenience that the iron wires or the iron filing contained in the mass as a sparkling or equivalent agent became coated or destroyed by rusting, so as to greatly interfere with the satisfactory sputtering and sparkling of the magic candles; or the compound mass was liable to ferment, and thereby became unfit for use.

All these drawbacks referred to are avoided according to my invention by assembling such composition, as used in the previous art, and comprising a mixture of metal filings with firmly solidifyin carriers around the wires by pressing, whic may be done by any suitable kinds of machines. The mass in this case should possess a certain degree of plasticity or solidifying properties, and in view thereof the mass may either be moist, stiff without becoming a liquid paste, or it may be dry, the plasticity or solidifying properties being produced by a suitable selection of ingredients while inthe case of moist compositions they will be quickly desiccated by compression and solidification,

here to the wire without any possibility of crumbling of the composition or loosening of the wire, as is likely to occur in the case of compositions applied to the wire by dipping and by desiccation of the very moist coating applied thereto, inasmuch as in such 'cases the exterior dried crust of the coating prevents the thorough drying of interior portions next to the wire which, therefore, can never be securely attached in this manner. Inasmuch as it is possible in this mannor to manufacture a very large number of candles daily, say one hundred thousand, the machine necessitating merely the attendance of one operator, it is obvious that very important advantages both from the mechanical as well as from the economical point of view are produced, and the process of manufacture is much simplified and comparatively inexpensive. Then, there is the other advantage that the new method is very efficacious, inasmuch as substantially not a particle of the compound is going to waste.

The invention having been described in its ing thick, stiff, solidifiable combustible compounds onto a thin, incombustible support, pressing and moulding the compound while in contact with-the support and adheringly unite it thereto, and allowing the compound to solidify.

The method of manufacturing magic candles and the like, which consists in pasting a stiff, solidifiable dough of combustible compound, containing metal fillings upon a metal wire, compressing the compound while in contact with the wire and adheringly unite it thereto and causing it to completely solidify.
